For full-scale music and movie reproduction with life-like dynamics, the Precision 6.4 is the flagship floor-standing loudspeaker in the Precision range. This grand design combines the detailed imaging and communication of the new 150 mm (6") Precision Dual Concentric driver with the low frequency extension of the matching 150 mm (6") bass driver in a large volume cabinet for deeper bass reproduction. The substantial cabinet is loaded with a pair of Auxiliary Bass Radiators (ABRs), positioned above and below the active bass driver, to deliver deeper and smoother LF response.
